Comments let you talk about an email thread inside Slashy without forwarding it. Threads stay clean, replies stay private, and @-mentions notify the right person.

​
Adding a comment

Open a thread and click the comment icon in the thread header, or press m. A side panel opens with a comment composer. Type your message and press Enter to post it. The comment appears in the panel alongside the thread, timestamped and attributed to you.
Enter sends. For a line break inside a comment, use Shift+Enter.
Links in comments are clickable: a pasted URL or email address becomes a link that opens in a new tab. Select text and press Cmd+K to link it, the same as in compose. Your first comment on a thread shares it with your team. Each person belongs to one team, so there’s nothing to pick. Attach files to a comment the same way you would in compose: drag a file onto the comment composer or use the attachment button. Attachments stay scoped to the comment thread and are visible only to teammates who can already see the comment.

​
Commenting on highlighted text

Select any text in the email body and a comment icon appears next to the selection. Click it to open the comment composer pinned to that exact passage, so your teammates see precisely what you’re referring to instead of guessing from a general thread comment. The quoted passage renders above your comment, attributed to whoever wrote it. Long quotes are trimmed to keep the panel readable, so quote the specific sentence you mean rather than a whole paragraph.

​
Reacting to a comment

Comments support emoji reactions, the same way Slack does. Use them to acknowledge a comment without adding a new one.
  • On a comment with no reactions yet, hover it and a small circle appears beside the bubble. Hover that for one-tap access to the common emojis, or click it to open the full picker with search.
  • On a comment that already has reactions, the pills sit below the bubble with an add button at the end of the row.
Reactions you added are highlighted, and hovering a pill shows who reacted. You get one reaction per comment: picking a different emoji replaces your previous one rather than adding to it. Click your own pill again to remove it.
These are reactions on internal team comments, which are visible only to your teammates. They are never sent to anyone on the email itself.

​
Who can see a comment

Comments are private to people on your team who have access to the thread. That means:
  • Teammates you’ve @-mentioned on the thread.
  • Teammates who already have access to the thread.
People on the email itself (external recipients, the sender, anyone in To or Cc) cannot see comments. Comments never appear in the email body, never get sent, and never leak through reply-all. To show a thread to someone outside your team, use Share an email by link, which has its own separate comments.

​
@-mentioning a teammate

Type @ in the comment composer to open the mention picker. Slashy suggests teammates from your workspace. Pick one and the mention is inserted; they get a notification. If a teammate isn’t in the picker, they haven’t joined the Slashy workspace yet. Invite them from Settings → Team.

​
Notification behavior

When you’re @-mentioned:
  • You get a notification through every channel you’ve enabled for the Comments category (desktop, browser push, mobile, email digest).
  • The thread shows up in your “Mentions” view, accessible from the left sidebar.
  • The comment is highlighted with a yellow accent the first time you open it.
If a teammate adds a comment to a thread you’ve previously commented on but doesn’t @-mention you, you do not get a push notification by default. You can opt into “All comments on threads I’ve commented” in Settings → Notifications → Comments if you want that.

​
Assigning a thread to a teammate

Give a team thread one owner so everyone knows who is handling it. Open the thread and press i, or press Cmd+K and choose Assign to…. The owner shows on the thread and in your thread list, with a green check once they’ve marked it done. See Assigning threads.

​
Editing and removing comments

Hover a comment you posted to reveal the edit and delete actions. Editing keeps the timestamp; deleting removes the comment for everyone who can see it. Slashy does not show “(edited)” markers on comments. You can only edit or delete your own comments. To remove someone else’s comment, ask them.

​
Comments from the agent

The Slashy agent can read the comments on a thread and post its own, such as a summary of the conversation for teammates, when you ask it to from chat or through the Slashy MCP connection. Agent comments appear in the panel like any other comment and update live. They can @-mention teammates, and they are visible to the same people as any comment on that thread. Ask something like “Summarize this thread as a comment for the team” from the agent sidebar (d a). The agent can also assign the thread to a teammate. See Ask the agent to assign. To hand a whole thread to the assistant by email, see Assistant email.

​
Mobile

Comments are visible and postable from the iOS app’s thread view. The composer behaves the same way as desktop, including @ to open the mention picker. Long-press a comment to reveal edit and delete actions.
